Shark Werks 991 S Race Exhaust

Note: If your car did not come with the Porsche Sport Exhaust (PSE) and you are looking for a “mild” sound increase to your existing set up we have found that our alternative center replacement works well as a solution (keeping things quiet inside).

This is a very loud and aggressive exhaust system. It does drone on the highway and will not be suitable for most daiy driven cars. We do not recommend it for most people, and instead recommend either our center exhaust or the Tubi exhaust system as an alternative.

Following on from our well-received Shark Werks 997 GT3, Turbo and Carrera exhaust designs we have now applied our customary Shark-bite to the Porsche 991 Carrera S platform.

3-D CAD designed with optimal flow, fit, weight savings and sound enhancement, our system replaces the two side mufflers on any Porsche 991 Carrera S (3.8L only at this time), whether or not it has Porsche Sport Exhaust (PSE). By utilizing appropriately-sized diameter tubing and maximizing the length we achieved our desired sound and minimized resonance. Our direct bolt-on installs into the factory location without any modification or compromise and is completely reversible. An overall weight saving of 20 pounds is achieved with a more aggressive idle and outside bark with a deeper tone. On the inside you can expect more exhaust noise at lower RPMs with a more exciting pitch when the gas pedal is stomped on. The two side mufflers do not utilize a straight-through design causing the sound to be more muted than some would like. Expect slightly better performance due to optimized exhaust gas flow. For track-enthusiasts not only will you appreciate the motorsport-like sound but with our exhaust you also remove heat from side mufflers away from rear tires.

The factory OEM vacuum actuated sound valves in the center muffler which open and close under different driving conditions are retained, letting the Porsche’s engine growl when you want it to, and keeping it quieter when you need it to.

As with all previous Shark Werks exhausts this system is not only 50-state emissions legal but also does not cause any check engine lights (MIL Codes) as it is designed to continue to operate with the factory catalyst and emissions equipment.

Designed and crafted in Northern California, the Shark Werks exhaust utilizes stainless- 18 gauge T304 tungsten inert gas welded stainless steel with mandrel bends and factory equivalent hardware.

– Factory headers, catalysts side mufflers and valves retained
– 3-D CAD designed factory fit direct bolt-on replacing factory side exhausts
– Compatible with either the stock or aftermarket tips
– Use your “exhaust” button to divert routing to switch from flowing through the center to a direct “bypassed” flow
– Real 20 pound weight savings (stock muffler weighs 25 pounds each total) from the rear of the car.
– Long-tube design for sound
– Remove heat away from the rear tires at the track
– 18 gauge T304 tungsten inert gas welded stainless steel mandrel-bent C.N.C construction for durability and flow.

Please note:
This exhaust modification will make the car considerably louder. This will be more noticeable on cabriolet models. With all models, this exhaust may add drone and resonance at various speeds/RPMs, which may require the car to be driven in lower gears to reduce or eliminate.
